The activity of isocitrate dehydrogenase in E. coli is regulated by the covalent attachment of a phosphate group, which inactivates the enzyme. When acetate is the food source for a culture of E. coli, isocitrate dehydrogenase is phosphorylated. However, when glucose is added to the culture, the phosphate group is removed from isocitrate dehydrogenase. These observations indicate that acetate metabolism proceeds through the citric acid cycle *, while glucose metabolism proceeds through the gluconeogenesis pathway

Organic Chemistry of Metabolic Pathways

Metabolic pathways allude to the arrangement of chemical catalyzed reactions that lead to the transformation of a substance into the final product. Metabolic pathways incorporate a progression of reaction where the substrate is changed continuously and the transitional metabolites are persistently recovered.

Glucogenesis

Glucogenesis is a metabolic pathway in which glucose is produced from carbon substrates that are not carbohydrates. This process is observed in plants, animals, fungi, bacteria and other micro organisms. The general  definition for glucogenesis or gluconeogenesis is as follows,
